| Abstract: | The basic theory of Gabor transform is first introduced, and an adaptive noise reduction method based on Gabor transform is presented. Then the de-noising results are researched by simulated signals, and the result of wavelet de-noising is compared with the adaptive de-noising method. At last, this new method is applied to analyze the measured signal from gear-box and the result shows this method can diagnose the fault information under strong noise. |
